The 'search' (Ctrl-F) capability works when adding a torrent.

But once the torrent starts, the Ctrl-F capability is broken -- the search text box appears! -- but when 'Enter' is hit, nothing happens.

Addendum: I have investigated this a little further, and discovered that it not the SEARCH that is broken, but the search OPTIONS.

Once the torrent is running, the search OPTIONS change the 'search':
* from "match anywhere within a line"
* to "match from beginning of line'.

This is obviously an OVERSIGHT or BUG, so should be rectified easily.
